About these instructions

Read these instructions before assembly and before using the compressor. This will avoid misunder-

standings and prevent damage. Improper assembly and use of the compressor can result in serious

or fatal injury.

Observe the safety instructions contained in these instructions.

These instructions must be passed onto the end customer along with the unit in which the compres-

sor is installed.

1|Safety

These assembly instructions describe the standard version of the HG22P R410A manufactured by

Bock. The compressor is intended for use in refrigeration systems in compliance with the limits of

application.Onlytherefrigerantspeciedintheseinstructionsmaybeused.

Any other use of the compressor is prohibited!

The Bock refrigerating compressor named in the title is intended for installing in a machine (within

theEUaccordingtotheEUDirectives2006/42/ECMachineryDirective,97/23/ECPressureEquipment

Directive and 2006/95/EC – Low Voltage Directive).

Commissioning is only permissible if the compressor has been installed in accordance with these

assembly instructions and the entire system into which it is integrated has been inspected and

approved in accordance with legal regulations.

1.4 Intended use

WARNING! The compressor may not be used in potentially

explosive environments!

- A minimum running time of 3 min. steady-state condition

(continuous operation) must be achieved.

For operation with supplementary cooling:

- Use only oils with high thermal stability.

- Avoid continuous operation near the threshold.

Foroperationwithfrequencyconverter:

- The maximum current and power consumption must not be

The pipe connections have graduated inside diameters so that pipes

with standart millimetre and inch dimansions can be used.

The connection diameters of the shut-off valves are rated for maximum

compressor output. Theactualrequiredpipecrosssectionmustbe

matched to the output. The same applies for non-return valves.

ATTENTION! Do not solder as long as the compressor is under pressure.

Superheating can damage the valve. Remove the pipe supports

therefore from the valve for soldering and accordingly cool

the valve body during and after soldering.

Only solder using inert gas to inhibit oxidation products (scale).
